DESCRIPTION

The ADC14DC080 is a high-performance CMOS

analog-to-digital converter capable of converting two

analog input signals into 14-bit digital words at rates

up to 80 Mega Samples Per Second (MSPS). These

converters use a differential, pipelined architecture

with digital error correction and an on-chip sampleand-

hold circuit to minimize power consumption and

the external component count, while providing

excellent dynamic performance. A unique sample-

and-hold stage yields a full-power bandwidth of 1

GHz. The ADC14DC080 may be operated from a

single +3.0V power supply. A power-down feature

reduces the power consumption to very low levels

while still allowing fast wake-up time to full operation. The differential inputs provide a 2V full scale

differential input swing. A stable 1.2V internal voltage

reference is provided, or the ADC14DC080 can be

operated with an external 1.2V reference. Output

data format (offset binary versus 2's complement)

and duty cycle stabilizer are pin-selectable. The duty

cycle stabilizer maintains performance over a wide

range of clock duty cycles.

The ADC14DC080 is available in a 60-lead WQFN

package and operates over the industrial temperature

range of ?40°C to +85°C.
